FIELD

The present disclosure relates to the field of display technologies, andmore particularly, relates to a liquid crystal display (LCD) panel.

BACKGROUND

Data black matrix less (DBS) technologies, featuring fewer blackmatrices on data lines, are widely used because they can effectivelyimprove alignment precision between an array substrate and a colorfilter substrate to prevent light leakage due to an alignment errorbetween the array substrate and the color filter substrate. In addition,the DBS technologies enable voltages to be individually input intoindium tin oxides (ITOs), thereby adjusting voltages during an alignmentprocess or a display process. Therefore, the alignment process can beoptimized and image quality can be improved. In conventional DBStechnologies, ITOs are parallelly connected to each other on an entiresurface and are connected to a single external pad, thereby adjustingthe entire surface with the single pad.

Domain-reduction pixel structures, which can effectively improvetransmittance, have attracted great attention, and a problem ofasymmetric viewing angles can be well compensated by appropriatelyarranging pixels. However, dark lines of the domain-reduction pixelstructures are extremely difficult to be converged, which significantlyaffects efficiency of increasing transmittance. Therefore, viewingangles are difficult to be compensated, resulting in difficulty of thedomain-reduction pixel structures to be applied.

In conventional alignment processes, a uniform potential is realized bydisposing multiple DBS electrodes on an entire surface, and the DBSelectrodes are generally connected to common electrodes on a side of acolor filter substrate. However, during practical alignment processes,an operating space is small, so that dark lines of the domain reductionpixel structures are difficult to be converged.

As a result, following problems in conventional LCD panel technologiesneed to be urgently solved: in LCD panels having DBS shieldingelectrodes and large domain-reduction pixel structure, dark lines ineach of sub-pixel units are extremely difficult to be converged due toasymmetric viewing angles, affecting display quality of the LCD panels.

Regarding the technical problem: the present disclosure provides an LCDpanel to solve following problems: in LCD panels having DBS shieldingelectrodes and large domain-reduction pixel structure, dark lines ineach of sub-pixel units are extremely difficult to be converged due toasymmetric viewing angles, affecting display quality of the LCD panels.

The present disclosure provides an LCD panel, more specifically, asshown in FIG. 1 to FIG. 6.

Conventionally, a domain-reduction pixel structure with a plurality ofDBS light-shielding electrodes is applied to LCD panels to improvealignment accuracy of data lines to block light, and simultaneouslyincrease transmittance of the LCD panels. However, because a width ofeach of sub-pixel units remains unchanged, driving voltages at two sideof each of the sub-pixel units remain unchanged during an alignmentprocess of liquid crystals. Therefore, a number of liquid crystalsoriented in a same direction is increased, resulting in liquid crystalsin a middle portion having relatively low deflection voltage, whichmakes the liquid crystals in the middle portion difficult to be orientedand leads to dark lines appearing in each of the sub-pixel units.Furthermore, conventionally, voltages applied to an entire surface ofDBS electrodes are equal, and are also equal to voltages applied tocommon electrodes on a side of a color filter substrate, leading tosmall operating space in practical alignment processes. Therefore, darklines are difficult to be converged in a same direction. That is, thedark lines occupy too much space and affect display quality of the LCDpanels. As a result, the present disclosure provides an LCD panel tosolve the above problems.

Please refer to FIG. 1, a structural schematic view showing a firstpixel structure of the LCD panel according to an embodiment of thepresent disclosure is provided.
